I just finished installing my Motorad 180 tstat, my advice to anyone doing this is buy a gallon of Mopar coolant, your gonna need it. Install took about 10 minutes.

After I was done refilling the coolant etc I wanted to see the numbers under the low speed fan relay so I pulled it while the car was running, guess what?
The ECU see's that as a low speed circuit coolant fan failure and turns on the high speed fan relay 100% and yes you get a CEL, thanks Dashhawk for clearing my CEL, this thing has paid for itself 10 times over and even more so mine was FREE!

So there you have the cheapest fan mod, pull the low speed fan relay.

Do you need the Dashhawk to clear the CEL? I would hope sticking the relay back in and running for a short time would auto clear.
